The block is providedin its upper side with the gr-cove -M-which extends longitudinally; thereof; "The atively thickforwardportions a! and relativelyi thin: rearward' port/ions l-4b.-f Therear end o the shank 15 of a toothbrush l l i's pivoted'yas :sat-1 8 toand between the flange portions l4a for movement into folded or extendedposition with relation to the block l3. The brush i6 is provided withthe usual bristles l1. The flanged portions Ma have provided at theinner sides and near their forward ends with lugs Me which are locatedin notches 15a of the brush shank l5 when the brush is in extendedposition. The block I3 is provided at its lateral side near its forwardend with a lug 23 which hasa snug fit in a slot 22 formed in the casingI 0. I

When in extended position, the brush 5 is arranged for use. It is heldin this position against any accidental movement with relation to thecasing l0 and, block l3 by the ribs Ma, lugs 14c and casing Ill. Thecasing l0 and block I: are held against any accidental-movement one withrelation to the other by the lug 23.

The casing I0 is provided with inner longitudinal ribs 19 which extendlongitudinally thereof and which contact with the rear ends of theflange portions Ma of the block l3 and with the upper edges of theflange portions Nb of the block, whereby to limit the insertion of theblock into the casing and to assist the lug 23 in holding the blockagainst any accidental movement 7 I with relation to the casing. Whenthe brush I6 is in folded position, the shank with the brush is locatedbetween the flange portions Ma and Nb and the ribs 19, and the bristlesI! are located rearwardly of the block l3.

The block I3 is provided with a bore 13a which is fully open at its rearend and Which is fully closed at its front end. The bore l3a adapts theblock l3 to receivea vial 20 containing dentifrice.

The front end of the vial 20 is closed bythe closed end of the bore l3a,and said end of the vial is screw threadedly engaged, as at 2|, with:

the wall of the bore. The vial 28 has a suiiiciently snug fit in thebore |3a to prevent it from" having any lateral movement with' relNormally the brush I6 is folded and'the vial is sealed in the block [0,which is'confined within the casing Ill. The lug 23 protrudesslightlybeyond the outer face of th casing 10, 20

so as to enable the removal of the body [3 therefrom toliave the brush[6 unfolded orextended fo'ra 'After the unfolding of the brush 1B or theextending thereof on removal of the block it, the latter is replaced inthe casing l0, thus holding thebrush fixed in its extended or'unfoldedposition for use. I v

v In Figures '7, 8 and 9 a slightly modified form ofjthe compact isshown. This form of the compact 'difiers from the one shown in Figures 1through 6 and 10 and 11, in that the' block, here designated 24 isadapted to receive adrawer containing a powdered dentifrice. The drawer25 is provided at its rear end with a pull 26, and it is held againstaccidental rearward movement from the block 24 by ribs 21 formed withinand extending longitudinally of the casing HL' The ribs 21 are locatedon the lower side of the casing l0 and contact with the rear end of thedrawer 25. As shown in Figure 9, the brush I6 'may be supplied withdentifrice after the withdrawal of the block 24 from the casing ID andbefore swingingthe brush into position for use. The ribs 21 make itimpossible for the drawer 25 to occupy a partly opened position when theblock 24 is in prevents any waste place in the casing Hi. This of thepowdered dentifrice.

What is claimed is:

1. A dental compact comprising a casing open at its forward end, a blockremovably positioned in the end, the block being provided at its upper 5side with relatively spaced flanges, a brush having a shank pivoted toand between said flanges for movement into folded or extended positionwith relation to the block, and lugs formed on the inner side of saidflanges forwardlyof said pivot, the brush shank being provided withnotches receiving said lugs when the brush is in extended position withrespect to the block and is held engaged therewith when the latter issubsequently positioned in the open end of the casing.

la 2. 4 dental compact comprising a casing open =at;its"forward end, ablock removably positioned in the fo ward end portion of the casing, andprovided*withspacedflanges, a brush having a shank pivoted to andbetween said flanges for movement into folded or extended position withrelation to-the'block,and ribs carried by the casing and extendingrearwardly from saidflanges to align the brush in its folded positionupon the block.

3. A dental compact comprising a casing open at itsforward end, a blockremovably positioned in the forward end portion of the casing, a brushhaving ashank pivoted to the block for movement into folded or extendedposition with relation thereto, theca'singbeingprovided at its front endwith a slotfand a lug carried by the block and engaged with said slotto'facilitate the separation of the casing and the block.

v 4'. A dental compact, comprising a casing open at one end, anelongated block positioned in the open end of the casing and extendinginto the casing a distance short of the otherend to provide an opencompartment, the block having spaced'parallel flanges, a brush pivotedto and between the flanges adjacent one end'of the block andmovable to'an active' position to extend one from the end of the block and thecasing, and to a closed position overhanging the other end of the blockwith theibristles located in the compartment, and the casing beingprovided at its 5 open-end with a slot, and a. lug carried by the block.and engaged'in said slot to facilitate th separation of thecasing andthe block.
